To'all wkom'it may concern: I 1 .1

Be it known that I, Louis BEnNnARD, a citizen of the United States and resident of Boston, in the county of Suifolk and btate of Massachusetts, have invented anew and useful Device for Holding Doors and the like, of which the following is a specification.

The principal object of my invention is to provide a holding device which will grip the floor or other fixed element with very great power.

A feature of my invention is the use of mechanical means to operate the device with positive action.

Another feature is a rotary member to force another member longitudinally into engagement with a floor or other fixed ele ment.

Another feature is a longitudinally movable member which includes a spring.

Another feature is a spring to disengage the device from its holding position.

Other features will be pointed out below.

In the drawing- Figure 1 is a central vertical section, partly in elevation, of a device embodying my invention; and

Fig. 2 is an elevation on a smaller scale, showing my device attached to a door.

Door A is suitably hung in adjacency to floor B. Screws 0? d pass through the wings (1 d of clamping member D and hold. the latter to the door. This clamping member is made in one piece of metal, and, in addition to said wings, comprises a tubular portion 03 and two vertical portions d and d, the former merging into wing 61 and the latter into wing d these vertical portions being connected by clamping screws d and d, which, when screwed up, draw said vertical portions together and force said tubular portion at to rigidly grip tubular member E and thus hold the latter in fixed relation to the door, said tubular portion d extending about seven-eights of the wav around member E.

Member E is externally threaded at e, and

is slotted at opposite sides at e e and is provided with an eye 6 Within member E is a longitudinally movable member in three parts F, F and F Part F is a metal tube and is provided at the bottom with a recessed head 7 which carries a projecting rubber portion 7" to engage the floor, said part F having threaded Specification of Letters Patent.

openings at opposite sides to engage the threading of screw Wand-being provided with a fixed pin f around which is bent one end of part F which is a strong coiled spring, the other end of which is bent aroundjpin f fixed to p'artF the latter being preferably a metal tube. The head of screw F preferably projects into slot 6 and the shank extends through slot e so that rotary movement of parts F is prevented.

Actuating member G is in the form of a socket internally threaded at g to engage the threading e, the portion g engaging the top of part F and integral wings g g being provided on member G for convenient rotation of the latter.

A'coiled spring H is connected at one end to eye a and atthe other end to screw F and tends to lift member F, and consequently portion f away from the floor.

When the parts are in the position shown the spring H holds the rubber portion f about a quarter of an inch from the floor. When it is desired to move portion f into holding engagement with the floor, member G is rotated by wings g and g or otherwise and the longitudinally movable means F, F and F are forced downwardly so thatportion f engages the floor under great pressure and this pressure may be adjusted by more or less rotation of member G, which member not only actuates the longitudinally movable means but also retains said means in the holding position.

When the door is to be freed member G is rotated in the opposite direction and spring H will lift part F so that portion f will no longer engage the floor or the ground, my device being particularly useful for heavy doors of garages and in such case portion 7" would engage the ground. Spring H will tend to resist the downward movement of part F but this resistance is negligible as compared with the power exerted by member G and by spring F which is much stronger than spring H.

What I claim is:

1. A device for the character described comprising a threaded support adapted for fixed connection to a door or the like; means mounted to move longitudinally on said support, the latter and said means having cooperating portions which prevent rotation of said means, said means including a PAT NT OFFICE.-

spring; a threaded actuating member engage ing the threading of the support, rotatable on said support and engaging said means to move said means -i-nto-- engagementii Withlah fixed element and to hold said means in such engagement; and a spring tending'tomovesald means out of engagement With SiLlCl' fixedieleinent'. v a
